opening pop-ups and controlling positions w/ max

i’m working on a theatre project, and I’m trying to open pop-up windows in
a specific position with max (to a secondary monitor / projector). Can
anyone recomend a useful approach or set of objects to accomplish this?

The [thispatcher] object can position windows – I’ve used it to pop
up floating dialog-style windows under the mouse pointer. If you’re
using OS X then you have a virtual desktop coordinate system which is
dependent on the monitor positioning (so tracking the mouse pointer
might be a good idea); I don’t know what Windows does.
